Nonlinear phase shifts induced by second order optical nonlinearity for their use in quantum information processing Ghent University
Quantum information processing would greatly benefit from the possibility to deterministically entangle photons. This is currently possible only with very complex systems that typically need to operate at low temperature and in high vacuum (Rydberg atoms for example) and are consequently extremely challenging to scale up to large systems. After nearly two decades of existence, the field of nanophotonics (silicon photonics) has recently seen ...
Frequency upconversion of single photons for on-chip quantum information processing. Ghent University
Optical treatment of quantum information relies heavily on single photon detectors. Tremendous progress has been made in the past decade to integrate such detectors to photonic chips and to efficiently detect single photons at wavelengths suitable for fiber telecommunications. The state-of-the-art superconducting detectors unfortunately still require a prohibitive cryogenic cooling. Here we propose to develop single photon detectors based on ...
Hardware efficient microarchitecture and quantum error correction codes for large scale quantum processors KU Leuven
With the recent demonstration of quantum supremacy, quantum computing is entering the era of Noisy Intermediate Scale Quantum computing (NISQ), where dozens to several hundreds of artificial quantum objects interact in such a way as to perform computationally intractable yet trivial tasks such as simulating their own behavior [1]. Yet, even the most optimistic estimates assume that many millions of qubits will be required for properly ...
Making a quantum computer talk chemistry: conceptual open quantum systems as insightful tools for quantum computing approaches to quantum chemistry Ghent University
Quantum computers have the potential to revolutionize quantum chemistry because they can, in principle, compute accurate electronic structure models very efficiently. At the moment, however, we are technologically limited to so-called ‘noisy intermediate-scaling quantum' (NISQ) devices, which suffer from calculation errors (noise) because they are very sensitive to their environment. Despite these noise issues, accurate molecular energies can ...

Development of a quantum dot single photon source on Silicon for the next generation integrated quantum circuits Ghent University
Quantum technologies have received much interest in the last years thanks to the promise of extreme computational power and secure data transmission. Single photons are important elements for these technologies, being suitable candidates both for quantum computing and communication. This triggered the research community to develop an ideal single photon source (SPS). Devices based on InAs quantum dots (QDs) grown on GaAs substrates are the ...
